Why COLD water?
I know that oil and water don't mix, but wouldn't there
be at least more *partial* mixing with HOT water?
If the oil/grease doesn't mix at all, it seems
to me that it'd be more likely to stick to
the walls of the pipe. True, or not true?
In cold water, food grease tends to solidify in little lumps and is
more likely to flush through without sticking to the walls of the pipe.
In hot water, food grease can liquify and leave a thin film on the
inside of the pipe that remains after the water finishes draining. The
grease film builds up in layers until blockage occurs.
Using cold water just helps get the grease past good pipes in your
house. It will still accumulate in low spots, especially when it gets
to the city pipes in the street where the water speed is slower.
Periodic flushing with large amounts of boiling water can melt grease
layers, but it only works well if you do it regularly before large
Here's a link to Al Carrell's homemade drain cleaners for preventive
maintenance (not for opening a clog):
I don't know if this is related to your problem, or not, but every
fixture in your house has a vent to the roof. They combine the
fixtures in one bathroom, and for this reason and others try to put
the various sinks, toilets, showers on top of each other, so that most
houses only need one or two such vents. That's why you have those two
little pipes coming out of your roof. They are not chimneys for the
mice's fireplace, like so many people think.
I see in a later post that you pour the water in when the pipe is
disconnected and there is no trap between the pipe and where you put
the water in. I guess that should duplicate the purpose of the vent
and it's not the vent.
I've never been in this situation, but my ugess is you need to attach
something bigger to the snake, like a sponge, or something that will
fill the pipe and not just push a hole through which gets filled up
again as the snake passes through.
I don't know anything about pequa.
Oh, yeah, ventilation. Somehow snake the pipe to the roof. Or from
They used to sell a garden hose attachment that swelled up as a ball
and was supposed to fit tightly in a pige. I don't know if you need
that or not.
I don't know what happens if you attach a sponge and then the sponge
comes off!!! In the middle of some pipe. LIke I say, I've never
Perhaps there is cooking grease gumming up the pipe. This would allow snake
to go through but retain water. Maybe hot water would flush it open?
I still see that stuff in hardware stores. You may also need to buy an
adapter to connect garden hose to the kitchen faucet.
If this still doesn't work, you could call a plumber with a drain pipe
camera, or use a pressure washer with a jetter hose.
That is a picture of a spade blade used on the leading edge of a snake. Far
more effective that the corkscrew type.
